GOLDEN, a citizenjof the United Sta 61' siding at Oakland, in the county of Alameda and State of-California, have invented: new and useful Improvements lnjOsclllators,

of which the following a specification. V This invention relates to anoscrllator for the production of high frequency osclllating currents for use in connectionwith radio telephones, telegraphs, land the like.

tion is to provide a simple, compact, easily connection with apparatus producing high;

frequency oscillating currents, said appa ratus being greatly reduced 1 1n vsize ;,and weight and design to employonly onepa r of electrodes to producethe same amount of smooth, uniform, high frequency oscillations formerly'produced by oscillators employlng several pairs of electrodes. 4 I y e 1 Otherobjects of the inventiorrwill be as followsrf g To employ metal electrodes subinergeddistilled iwia'ter, 'orla liquid wh ch 1s notff inflammable or "explosive in, any 'way,

which will-not produce objectionable fumes nor deteriorate with use, as is the case where alcoholis' employed.

Employing aspa k gap where electrodes are very close together .to "allow. the condenser discharges to pass between the electrodes'rwithout creating toofmuch heat, or,

in other-words, wasting energy in the. form of heat in the surrounding liquid as well as in the electrodes.

To employ tubular electrodes 'which perjmit the'vapor Orgases formed to freely discharge, and furthermore, to provide novel means for circulating the distilled water,

Furtherobjec'ts will hereinafter appear.

will bereadily seen that the circuit connee tions are only of minor importaneeandare. merely shown to illustrate one of the uses The oscillator proper consists fof a cy-f of the; oscillator.

lindrical container lt provided with a coyer 15, preferably constructed of insulating ma;

'terial. Mounted on top of the cover is a stationary core-magnet 16 of suitable con struction. Extending through the "magnet is Bin l le core screw 17. Su pendBd from the cover are a'pair of rods 17 which are connected at intervals by cross bars 18, 19 and 20. The lower cross bar is provided. for the supportof the electrode B while the upper cross bars 18 and 19 serve as a guide fora rod 21, on the upper end of which is secured an armature 22 and on the lower end. theelectrodeC. The rod 21 is mounted in directalignment with the screw core 17 of the magnet 16 and as the armature is mounted on the upper end of the rod in close proximity to the'lower end of the magnet core, it can readily be seen thatthe rod and electrode carried thereby will be attracted and lifted by the magnet when ever this is energized. i s 7 By referring to Fig. 2, it will be, seen that the electrodes forming the spark gap are tubular in construction and that the lower electrode B is supported by a hollow base member 23 which'is connected with an elevated storage tank 24 by means of a pipe 25. Mounted on the pipe, outside of the tank 14 enclosing the electrodes, is a valve 26. This valve is opened and closed, by means of a magnet 27, as will hereinafter be described. The tank 2 1 is connected with the discharge side of a pump 28 of suitable construction and the suction side, of the pump is connected by means of a pipe 29 with an overflow opening 30 formed in the tank 14:.

In actual practice, I preferably employ electrodes constructed of tungsten metal and I also employ distilled water as a circulating medium. The-tank 24 is provided for the reception of distilled water and the pump 28 for the circulation thereof. That is, the distilled water flows to the electrodes B and G by gravity but as it overflows from tank 14:" through the opening'30, itis returned and delivered to the tank 24 by means of the pump 28. The electr'o-magnets which cause the raising and releasing of the upper electrode and the opening and closing of the valve 26 are connected in series by means of wires 30, 31 and 32, through a telegraph key 33 with contacts on the rheostat 3, as shown, which allows a by-path for thecurrent entering the oscillator to pass through said electro-magnets upon the pressing of the key 33. l/Vhen the key is released the upper electrode C drops and upon striking the lower electrode destroys the spark gap produced by the separation of the electrodes and thereby the creation of succeeding oscillations until the key is again pressed.

The pump 28 is driven by an. electric motor 35. This motor is connected with the oscillating circuit in practically the same manner'as the electro-magnets 16 and- 11 .t 7 When the generator c1rcu1t switch 215 closed, the current will flow through the rheostat and the pump'motorby path to the choke coil 4; then through the connected electrodes to the return choke coil 5, back to the generator. Upon depressing thezkey the production of thespark gap, thus prothe valve to ducing oscillations through the highfre quency circuit. Water is at thesame-time t admitted,due to the opening of the v'alve,.

and as the electrodes are tubular and hollow,

as shown, it can readily be seen thatthe water entering through tube 25 and.the1ho1-,

low base 23, will pass upwardly through the electrodes and out through a discharge open ing 40, finally overflowing through the out"- A portion of the water admitted by the pipe 25 is also permitted to escape between the faces of the electrodesand it istherefore .85 let 30, from where it is returned by means of the pipe 29 and pump 28 to the tank 24.

obvious that any gases or steam produced I will be instantly liberated, either through the center of the electrodes or 'exterioriof the same. The circulation of distilledwater thereforeinsures cooling of the electrodes as well as instant removal of any vapor formed by the spark discharged betweenthe faces:

of the electrodes, thereby permitting the production of smooth, uniform, high frequency oscillations formerly onlyproduced by oscillators employing several pairsmf,

electrodes.

Electrodes constructed of tungsten metal" burn away very slowly. f Comparatively l little adjustment is therefore required: and

as this is accomplished by regulatingthe screw 17, it is possible to readily re-adjius't the spark gap whenever required." The oscillator connected as here shown, may be used for radio telephone work, if desired, by opening switch 12 and closing a switch 12, which: 7 serves the function of bridging key 33, or

the station may be employed for radio:tele

graph work by closing the switch 12 'and 7 opening the switch 12 it being ,unde'rstood,'

however, that the main switch'2in the direct current circuit, must first be closed when it is desired to operate the station.

The change from telephone to telegraphic service is practically instantaneous as it is only necessary to operate the switches 12and.

12 to change the current flow through the different instruments employed.

While the structure here'shown is more or less speclfic, I wish it understood'that. various changes in form, proportions andminor details of construction may be re- I sorted to within the scope of the appended claims; similarly, that the materials and finish of the several parts employed may be such as the experience and judgment'of the manufacturer may dictate.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In an oscillator, a pair of-electrodes, means for circulating a liquid through and between the electrodes, means for contacting and separating the electrodes, and means cooperating with said last mentioned means for stopping the circulation of, liquid through the electrodes. when they contact, and for re-establishing the circulation when the electrodes are separated. Y
